Live so that others quote you

For it’s disgraceful for an old person, or one in sight of old age, to have only the knowledge carried in their notebooks. Zeno said this…what do you say? Cleanthes said that…what do you say? How long will you be compelled by the claims of another? Take charge and stake your own claim—something posterity will carry in its notebook.

Seneca, Moral Letters, 33.70
